Catchable fatal error on 3.6 update

Question

Trying to debug the situation. Getting close, but will need a little help!!

Here is the error:

Catchable fatal error: Object of class WP_Error could not be converted to string in /home/website/public_html/wp-content/themes/Alexia/lib/functions/common.php on line 97

And my code from the error:

// no cache files - let's finally resize it
        $new_img_path = image_resize( $file_path, $width, $height, $crop );
line 97-->      $new_img_size = getimagesize( $new_img_path );
        $new_img = str_replace( basename( $image_src[0] ), basename( $new_img_path ), $image_src[0] );
        // resized output
        $vt_image = array (
            'url' => $new_img,
            'width' => $new_img_size[0],
            'height' => $new_img_size[1]
        );

        return $vt_image;
    }

    // default output - without resizing

Thanks in advance NINJAS!!

image_resize (deprecated) is returning an error object so really, the problem is here: $new_img_path = image_resize( $file_path, $width, $height, $crop ); Something is wrong with that line and you are not checking whether the return value is an error object or a string before trying to use the return value as a string.

You did not post any code that might help me work out what is wrong with $new_img_path = image_resize( $file_path, $width, $height, $crop ); but at the very least you should do:

$new_img_path = image_resize( $file_path, $width, $height, $crop );
if( !is_wp_error()) {
    $new_img_size = getimagesize( $new_img_path );
    // ...

Converting to use WP_Image_Editor would be wiser though.
